Leaves dying on zinnia

Asked July 9, 2020, 2:24 PM EDT

I have 4 Zinnia plants, each in a different pot. The "shorter" ones are fine. I have 2 taller ones that seem to be "burnt" on the leaves. All in a mostly sunny area. Can you tell me what the problem might be?

Without seeing sharp photos of the affected leaves we can't account for their condition.

However, here is information about some things that affect zinnia leaves:

I did send a pic (or thought I did)
I'll try again

We can't see definitive evidence of leaf spot diseases in the photo. What we do see suggests that watering (too much, too little or a combination of both) might be stressing the plant.

Too much fertilizer also causes brown leaf edges.
